Yes @Fab we have similar, two different Cinema brands here do that. One of them I've been to:
ACE Cinema - Gold Lounge
You get a small soft-drink and bowl of popcorn included in the price of your ticket. There is a special lounge you wait in before heading into the Cinema and as you said you can order expensive hot snacks and meals to be delivered to you at certain intervals (start, middle of movie, etc.) And you can order a drink or two (alcoholic) if that's your sort of thing.
The seats in this one are similar to what you described. Mini table in-between and large electronic recliners on the sides.
However where this differs is you share the same cinema as the normal patrons... the special Gold Lounge area is just in an elevated position towards the back...
It was good fun going Gold Lounge, did it a few times but really it's more for an intimate setting with your partner.
So in my opinion:
Pros:
Much more comfortable seating!
Hot food and snacks at extra expense
Table is handy, also has a button to call staff.
Cons:
Food quality is not worth the premium price... for that price you could spend that on a much better quality restaurant meal BEFORE the movie
Same cinema as the normal patrons, so same audio/visual experience
IMO, for that price you would get much better value spending it towards an IMAX ticket instead. And you'd still have leftover money for desserts at the cafe next door.
